SHEET-METAL VIINDOW.

Specification of Letters Patent.

Patented Dec. 6, 1910.

Application filed April 14, 1909. Serial No. 489,794.

To all whom it may concern:

Be it known that I, ALEXANDER FROM- HOLD, a citizen of the UnitedStates, residing at the borough of Rutherford, county of Bergen, andState of New Jersey, have invented certain new and useful Improvementsin Sheet-Metal lVindows, of which the following is a specification. Thisinvention relates to improvements in sheet metal windows and refers morespecifically to improvements in the stops or guides whereby the sash areconfined and guided.

Among the salient objects of the invention are to provide extremelysimple, cheaply constructed and entirely reliable means of adjustablysecuring the stops in their seats in the window frame; to provide insuch mechanism means for adjusting one or more of the stops laterally,2'. 6. toward or from the sash frame without in any degree impairing thereliability with which the stop is secured in position and withoutsubstantially adding to the cost of construction; and in general toprovide improvements in the stop mechanism of a window of the char- 1acter referred to.

To the above ends the invention consists in the matters hereinafterdescribed, and more particularly pointed out in the ap pended claims.

In the drawingsFigure 1 is a fragmentary perspective View showing inperspective a portion of one of the side frame members and fragmentaryportions of the upper and lower sash seated therein; Fig. 2 is a crosssectional view of the window frame shown in Fig. 1; the sash beingomitted; Fig. 3 is a detail cross sectional view of the adjustable stopmember and the parts of the frame within which it is seated; Fig. at isa longitudinal sectional view taken centrally through the detachableparting strip stop.

Referring to the drawing, 1 designates as a whole a. side casing memberof a sheet metal window frame, which is in its general constructionsimilar to those now in common use. In the innerface of the frame memberare formed two parallel grooves, as 2 and 3 adapted to respectivelyreceive an adjustable stop at and a detachable parting strip stop 5. Anintegral outer stop 6 is also shown.

Describing first the adjustable stop 4, the walls of the groove 2 formupon the interior of the hollow frame 1 a rib 7, and at frequentintervals apart, say at intervals of one foot, are inserted through thisrib metal strap-like anchors 8; these anchors being inserted looselythrough suitable slots 9 in the opposite sides of the rib 7 in positionto hold the anchors 8 parallel with the inner face of the framemember 1. Each anchor is suitably apertured about midlength and threadedto receive the end of a screw 10 inserted through the outer face wall ofthe stop; the anchors being set far enough above the bottom of the stopgroove so that the end of the screw will not encounter the bottom of thegroove when extended slightly through the anchor. The adjustable stop ismade considerably wider than the width of the stop groove which itoverlies and preferably has only one of its side members or wallsextended into the groove, as indicated at 11. This extension 11constitutes a stop which limits the movement of the stop memberlaterally in one direction by encountering the side wall of the stopgroove, while the body of the screw 10 by encountering the opposite sidewall of the groove limits the movement of the stop laterally in theopposite direction. These two limits of movement are such as to preventthe stop member from being moved in either direction sufliciently toexpose the stop groove. IVhen it is desired to adjust the stop toward oraway from the sash, the series of screws which engage the anchors aresimply loosened slightly, thus freeing the anchors so that they mayslide endwise, whereupon the stop may be forced over laterally to anydegree within the limits of adjustment described. Having been properlyadjusted, the screws are tightened, and by drawing the anchors againsttheir seats in the rib 7, look the stop in adjusted position.

Describing, now, the detachable parting strip stop, the internal rib 7which forms the groove 3 is apertured and provided with a series ofanchors 12 constructed and ar- -ranged substantially or precisely asdescribed in connection with the adjustable stop. In a substantiallysimilar way a series of screws 13 are inserted through the face wall ofthe parting strip and into the anchors 12, but in this instance the sidewalls of the or interfere with the anchors they are notched out, asindicated at 14-, in position to register with each of the severalanchors.

In order to reinforce the face wall of the parting strip, and at thesame time permit the heads of the screws 13 to be let into the strip, soas to lie flush with the latter, reinforcing strips 15 are inserted andriveted to the face wall at each side of each screw aperture, asindicated at 16. The heads of the screws are countersunk into the doublethick wall thus formed.

It will be obvious that the mechanism described fully attains theseveral objects of the invention hereinbefore stated. It will be furtherobvious that the details of construction and arrangement may be modifiedwithout in any sense departing from the spirit of the invention, andaccordingly the claims hereto appended are not to be understood aslimited to the specific construction shown, except in so far as they arespecific to de tails.

I claim as my invention:

1. In a window, a casing frame provided with a stop groove, a stopengaging said groove, and means for adjusting and locking said stop inany position of adjustment com prising an anchor plate slidably mountedin slots formed in the sides of said groove, and a. locking boltextending through said stop into said plate.

2. In a window, a casing frame provided with'a stop groove, a stopengaging said groove, a plurality of anchor plates slidably mounted inslots formed in the sides of the groove, and locking bolts extendingthrough I said stop into the respective anchor plates.

3. The combination with a casing frame, provided with a stop groove, ofa stop engaging said groove, and means for adjusting and locking saidstop in any position of adjustment comprising a laterally movable anchorplate seated in said groove, a locking bolt extending through said stopand engaging said plate.

4. In a window, a casing frame provided with a stop groove, the latterforming an integral rib, a stop engaging said groove and means forlocking said stop to the casing comprising an anchor plate movablymounted in said rib and a screw extending through I the stop and intosaid plate.

In a window, the combination of a casing frame provided with a stopgroove, a stop engaging said groove and having a right angled extensionextending into the groove, an anchor plate movably mounted in slotsformed in the sides of said groove, and a locking bolt extending throughsaid stop and engaging said plate.
